Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
1. Guiminer
guiminer is a powerful and easy-to-use bitcoin mining software for Windows system. The software is small in size and friendly in interface. As long as the user's CPU or GPU is strong enough, it can create a new miner on the interface and mine independently! In addition, guiminer is free software
a card, that is to say, it depends on the frequency and SP

the better the a card, the stronger the mining.
the World Gold Council (WGC) claims that the US Federal Reserve's interest rate increase may not have the adverse impact on gold price as many people think
the relationship between gold prices and interest rates is more complex than it appears and more fragile than in the past, the World Gold Council said in a report on Thursday
the association added: "other factors affecting the price of gold, including some positively correlated with economic growth, emphasize that gold is an important diversified asset and a portfolio asset for risk management. This role is becoming increasingly important as stocks and bonds are likely to provide below average returns over the next few years. "
in the past 12 months, market speculation on when the United States may choose to raise interest rates has been fierce. Since 2008, the Federal Reserve has kept the federal funds rate close to zero
although the Fed was initially expected to raise interest rates for the first time in a decade in June this year, a series of mixed economic data, low inflation rate and dovish comments on the US economic growth rate issued by Fed chairman Yellen delayed the schele of raising interest rates
when the federal funds rate really rises, the general consensus is that the price of gold will face heavy downward pressure, because the planned cost of holding gold will rise, thus prompting investors to turn to assets that provide income
the World Gold Council said: "however, jewelry and technology demand accounted for nearly 60% of the annual demand for physical gold. There is an indirect positive relationship between these markets and interest rates, that is, the periodic rise of interest rates is usually accompanied by the increase of economic growth and consumer spending
according to the World Gold Council, Europe and North America account for only 17% of global gold demand, and only 60% of it is related to investment
similarly, the view that US interest rate hikes affect gold prices is not as strong as before, because this situation is largely based on the market's analysis of the performance of gold prices and interest rates between the 1970s and 1980s. At that time, the economy was very different from what it is now
according to the World Gold Council, "the gold market is also different. Over the past decade, demand for gold in developed markets has fallen from more than 60% in the 1970s to less than 30%. Emerging market demand for gold accounts for 70% a year and is less sensitive to changes in US interest rates. In addition, the demand for jewelry and technology is largely Pro cyclical. "
in terms of investment demand, gold will continue to be a diversified asset
the World Gold Council said: "even when the nominal interest rate rises to 4%, gold has been quite effective in diversifying its portfolio and recing the risk of real interest rate."
according to the world gold association, the current real interest rate level in the United States is still very low and far below the threshold level. As of December 31, the real yields on three-month and one-year treasury bonds were - 0.73% and - 0.6%, respectively
the association said: "raising interest rates will not improve the outlook for fixed income assets. At the current yield level, the rising space of bonds may be limited, so it is not as effective as gold in easing equity risk. This helps to boost demand for gold, as some investors will use gold to supplement bonds when managing equity risk and diversifying their portfolios. "
as we all know, the well-known exchange is centralized, and the centralized system is not reliable. People who speculate in money have heard about the news that the exchange is running away with money, or that the exchange is attacked by hackers to steal money
compared with the exchange, wallet is a decentralized proct, which can really make your digital assets safe. If you master your wallet's private key and mnemonic code, you will be able to master your assets. Unless you disclose your private key and mnemonic code, you will be able to steal money
thirdly, the exchange does not have the function of storing assets, while the wallet can manage money and borrow money.
in the bear market period of the currency market, it is particularly suitable to put digital assets into the wallet to manage money, because most wallets have the function of managing money, and the income is considerable. According to the length of the investment cycle, the minimum income is 8%, and the maximum income can reach 30%. When the bull market comes, you can make money by trading it. In addition, the lending function of the wallet is also very good for coin friends. After the digital assets are mortgaged, other operations can be carried out, and the interest can also be redeemed
finally, with a wallet, you can collect money and candy
some tokens are also traded over the counter before they are listed on the stock exchange, and both parties need to have their own wallets
in order to ensure the safety of assets, long-term coin holders must have their own wallets. It is recommended that bitkeep wallets have multiple currencies and multiple mainstream exchanges
Notebook can be used for mining
most virtual currencies use a mechanism called proof of work (POW) to distribute rewards, and the core process is hash operation. So ordinary computers can also mine
ordinary computers can be used to dig bitcoin, because mining itself is just computing. Professional mining machines dig well, dig fast and earn a lot. Ordinary home computers dig slowly and earn less
for example, there are mature professional mining machines for mining bitcoin and lightcoin
extended data
because of adhering to the principle of server construction, the whole mining machine is miniaturized, and the specially designed mining chip is adopted, which is born for the optimization of bitcoin / lightcoin algorithm, with a single computing power of th / s level. However, in order to ensure stable operation, the chip will be covered with aluminum cooling fins, which will be blown through by the front and rear violent fans, but the noise is high, so it is usually placed in a factory
in addition, this kind of professional miner is expensive and uses customized chips. If you don't mine, you can't use it again. In short, you can't do anything except mine
however, if an ordinary computer is a little more professional in mining, it is necessary to select a motherboard specially designed for mining, for example, a motherboard with 10 PCI X1 interfaces, a PCI to USB expansion board and other hardware, and modify the graphics card BIOS at the same time, so as to achieve more powerful computing power and indirectly increase revenue
